The hugely popular Hadoop framework for processing big data sets is getting some serious competition from alternative platform Spark, the Wall Street Journal reports, and thousands of the upstart’s acolytes are expected at the Spark Summit in San Francisco this week. IBM is getting behind the Apache open-source project with an investment worth hundreds of millions of dollars in software developers and technology, the New York Times says.

Russian and Chinese intelligence agencies have reportedly decrypted files of former U.S. National Security Agency contractor Edward Snowden, and have identified British and U.S. secret agents. As a result, the U.K.’s MI6 has withdrawn agents from operations in hostile countries, according to a report in the Sunday Times of London. The story, based on anonymous sources, is however being widely lambasted as a political hatchet job, and Glenn Greenwald, a journalist who worked with Snowden to produce the blockbuster reports exposing NSA surveillance two years ago, said that the leaker insists he gave the files to journalists or destroyed them to prevent them from falling into the wrong hands.

The research by Localytics indicates that these days one in four apps are dismissed after one try, up from last year when one in five apps suffered that fate.

U.S. Labor Department will look at whether H-1B visas are being misused

In the wake of some well-publicized cases of U.S. tech workers being replaced with lower-paid IT staff brought in by outsourcing firms via the H-1B visa program, the U.S. Labor Department plans a probe into whether the practice is legal. The visa program is intended to allow companies to import workers when they are unable to find qualified U.S. residents, but it’s coming under fire as businesses apparently use it to simply lower their staffing costs. Meanwhile, at least one division of Disney appears to be backpedaling on such plans after articles in Computerworld and the New York Times reported that outsourced workers were compelled to train their replacements as a condition of severance.
